Abstract

Ce procédé d’exécution d’un programme d'ordinateur comporte : - l'incorporation (408), dans des métadonnées d'un bloc contenant une ligne de code à accéder à l'aide d'un pointeur, d'un premier identifiant de pointeur associé à la ligne de code à accéder, puis - l'obtention (166) d'un pointeur comprenant : - une première plage de bits contenant l’adresse de la ligne de code à accéder, et - une seconde plage différente de bits contenant un second identifiant de pointeur, puis - la vérification (176) que le second identifiant de pointeur contenu dans le pointeur obtenu correspond au premier identifiant de pointeur associé à la ligne de code à accéder et contenu dans les métadonnées du bloc chargé, et lorsque les premier et second identifiants de pointeur ne correspondent pas, alors le module de sécurisation déclenche (180) le signalement d'une faute d'exécution. Fig. 6This method of executing a computer program comprises: - the incorporation (408), in metadata of a block containing a line of code to be accessed using a pointer, of a first identifier pointer associated with the line of code to be accessed, then - obtaining (166) a pointer comprising: - a first range of bits containing the address of the line of code to be accessed, and - a second range different from bits containing a second pointer identifier, then - checking (176) that the second pointer identifier contained in the pointer obtained corresponds to the first pointer identifier associated with the line of code to be accessed and contained in the metadata of the loaded block, and when the first and second pointer identifiers do not match, then the security module triggers (180) the signaling of an execution fault.
